On the Right...for Military Spending

As a Modern-Conservative, I think the government has to do ensure three main things:
1.Domestic justice
2.Domestic rights
3.Domestic Tranquility

So, it confuses me terribly when my President [present or past] talks about leading a crusade to destroy radical Islamic terrorists on the other side of the planet. On September 11th, 2001--terrorists attacked the World Trade Center in New York. Suddenly, President Bush had a 90% approval rating [because obviously being POTUS while terrorists kill thousands of innocent people is something the American people approve of] and we were going to war in Iraq.

Why? Weapons of Mass Destruction. Them ol' WMD's were far too dangerous to Americans who live over 3000 miles away from Iraq [who doesn't even have half the rocket technology to get a bomb out of Baghdad]. So we went in, most people thought that the words Iraq, Osama Bin Laden, and terrorists all resided in the same place--along with them ol' WMDs[which seem to be invisible WMDs now].

People started getting pissed off about the whole thing, and then everyone hated Bush. Then President Obama came along, said he was going end the war in Iraq--and he's seeming to do that. The only problem with this is that he's bleeding more troops into Afghanistan every day. Our top generals say it'll take more and more troops to get the job done in Afghanistan. By the way, can anyone help me with the "job" that needs to get done in Afghanistan? I'm a little confused on that one...

While all this goes on, I have to ask myself what the purpose of even fighting on foreign soil when we seem to be extremely protected at home. I can't even bring my deodorant onto an airplane because secrurity is so tough and we're supposed to think radical Islamic terrorists are going to attack us? For a Conservative [not a Republican], it's safe to say that mainly defensive military spending is favorable when our Domestic Tranquility is far from threatened. If we had used the billions of dollars spent on the war in Iraq and Afghanistan on precautions that would prevent terroistic attacks on America--I wonder how much safer things would be...
